Abstract
Abstract The piece of furniture is adapted to constitute a bed which, in the folded position obtained by an easy maneuver ensuring the locking of the folded elements, presents very reduced overall dimensions. The bed base comprises two head elements followed by an horizontal element, an intermediary element and a final leg element. The locking in the folded position is ensured by side plates each directly pivoted on the intermediary element and, through links, on two legs the maneuver of which is automatically ensured when the bed base is actuated. The leg element comprises a flexible seating to be used in the seat position of the piece of furniture.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
337 words
A bed base for a piece of furniture adapted to be converted from a seat into a bed comprising a fixed frame, at least one head element, levers pivotally connecting said head element to said fixed frame in such a manner that said head element moves inside the back of the piece of furniture in the seat position, a main frame pivotally connected at its back end to said head element, an intermediate element pivotally connected to the forward end of said main frame, a leg element pivotally connected at one end to said intermediate element, a first leg, a bed base, means pivotally connected said bed base to said first leg at its upper end to said main frame in such a manner that said first leg folds under said main frame when said bed base folds from the bed position to the seat position, a second leg pivotally connected at its upper end to said leg element and capable of being folded forward along said leg element, a bar pivotally connected at one end to said leg element, said intermediate element having an inclined side slot, a pin on said bar slideably positioned in said slot for folding said leg element at right angles to said intermediate element, a control member pivotally connected at one end to said intermediate member, a transverse pin on the other end of said control member, said main frame having a side slot with said control member pin slideably positioned therein, a bar pivotally connected at one end to an intermediate part of said control member and at its other end to said second leg whereby the thrust exerted on said second leg at the end of the folding movement of said leg element brings said leg element parallel to said main frame causing the abutment of said transverse pin of said control member against the back end of said main frame slot and thus the locking in their folded positions of said main frame, intermediate element and leg elements.
Claim 2
Dependent Claim
337 words
A bed base for a piece of furniture adapted to be converted from a seat into a bed comprising a fixed frame, at least one head element, levers pivotally connecting said head element to said fixed frame in such a manner that said head element moves inside the back of the piece of furniture in the seat position, a main frame pivotally connected at its back end to said head element, an intermediate element pivotally connected to the forward end of said main frame, a leg element pivotally connected at one end to said intermediate element, a first leg, a bed base, means pivotally connected said bed base to said first leg at its upper end to said main frame in such a manner that said first leg folds under said main frame when said bed base folds from the bed position to the seat position, a second leg pivotally connected at its upper end to said leg element and capable of being folded forward along said leg element, a bar pivotally connected at one end to said leg element, said intermediate element having an inclined side slot, a pin on said bar slideably positioned in said slot for folding said leg element at right angles to said intermediate element, a control member pivotally connected at one end to said intermediate member, a transverse pin on the other end of said control member, said main frame having a side slot with said control member pin slideably positioned therein, a bar pivotally connected at one end to an intermediate part of said control member and at its other end to said second leg whereby the thrust exerted on said second leg at the end of the folding movement of said leg element brings said leg element parallel to said main frame causing the abutment of said transverse pin of said control member against the back end of said main frame slot and thus the locking in their folded positions of said main frame, intermediate element and leg elements.
Claim 3
Dependent Claim
83 words
A bed base as claimed in claim 1 including two head elements, a lever pivotally connected to said head elements, a pair of arms pivotally connected to said lever and said fixed frame, a grooved bar, a roller in said grooved bar, a roller arm carrying said roller and pivotally connected to said main frame, a small bar pivotally connected to said roller arm and said lever whereby the pulling forward of said main frame causes said head elements to be raised upwardly.
Claim 4
Dependent Claim
56 words
A bed base as claimed in claim 2 wherein support legs are pivotally connected to said main frame, small bars are pivotally connected to said support legs and said intermediate elements whereby said legs are automatically extended to vertical positions during sliding of said intermediate elements from the rear to the front of said main frame.
Claim 5
Dependent Claim
103 words
A bed base comprising a fixed base support, a main frame, a head element pivotally connected to said main frame, a first arm pivotally connected to said base support, a small bar pivotally connected to said first arm and to said head element where said head element is pivotally connected to said main frame, a second arm pivotally connected to said base support, a second arm pivotally connected to said second arm and said small bar, a bent control lever pivotally connected to said main frame, said second arm and a connecting arm pivotally connected to said second arm and said first arm.
Claim 6
Dependent Claim
103 words
A bed base comprising a fixed base support, a main frame, a head element pivotally connected to said main frame, a first arm pivotally connected to said base support, a small bar pivotally connected to said first arm and to said head element where said head element is pivotally connected to said main frame, a second arm pivotally connected to said base support, a second arm pivotally connected to said second arm and said small bar, a bent control lever pivotally connected to said main frame, said second arm and a connecting arm pivotally connected to said second arm and said first arm.
Claim 7
Dependent Claim
44 words
A bed base as claimed in claim 4 including a spring means connecting said first arm to said base support tending to draw said first arm towards the front of said base support in order to permit an easier unfolding of the head element.
Claim 8
Dependent Claim
30 words
A bed base as claimed in claim 4 including support legs pivotally connected to said main frame, connecting arms pivotally connected to said support legs and said bent control lever.
Claim 9
Dependent Claim
36 words
A bed base as claimed in claim 4 including a flexible seating on said support legs, providing a spring support for the bed base in the bed position and a cushion support in the seat position.
Claim 10
Dependent Claim
